  • Welding Operations
    WELDING OPERATIONS Date Initiated: February 1, 1993 Dates Modified / Updated: September 15, 1993 October 16, 1998 PROCESS DESCRIPTION: Many industrial and manufacturing facilities regularly use a variety of welding processes and materials. The processes include; - Gas Metal Arc Welding (GMAW) - a. k. a. Metal Inert Gas Welding (MIG), - Gas Tungsten Arc Welding (GTAW) - a. k. a. Tungsten Inert Gas Welding (TIG), - Shielded Metal Arc Welding (SMAW) - a. k. a. Manual Metal Arc Welding (MMA), - Flux Core Arc Welding (FCAW), - Submerged Arc Welding (SAW), - Arc Spot Welding, - Electrogas Welding, - Electrostag Welding, - Brazing, - Thermal Cutting, - Resistance Welding, - Plasma Arc Welding, - Electron Beam Welding, - Laser Beam Welding The majority of the common welding processes can be classified as either gas metal arc welding (GMAW) or shielded metal arc welding (SMAW). GMAW generally uses an electrical current to melt and apply a filler metal under a blanket of inert gas. SMAW traditionally uses an electrical current to melt specially coated electrodes which form a protective flux over the weld during application. Both processes use electrodes, filler metals, wire, coatings, and/or gases that may contain and emit several listed substances including NOx, CO, cadmium, cobalt, copper, chromium, manganese, nickel, lead, zinc, and fluorides. Welding operations release fumes and particulates with diameters of 0.001 to 100 microns. Previous studies of welding emissions have been primarily focused on worker exposure and safety. Many technical difficulties have been identified regarding proper sampling and analytical procedures due, in part, to the wide variety of processes, welding materials, and field conditions. The majority of existing test data which can be used to quantify welding emissions is based on studies performed by the American Welding Society (AWS).

  • Lecture: 3 Classification of Welding Processes II Apart from Technical
    Lecture: 3 Classification of Welding Processes II Apart from technical factors, welding processes can also be classified on the fundamental approaches used for deposition of materials for developing a joint. This chapter presents the classification of welding processes as welding processes and allied process used for developing a joint Keywords: Welding and allied processes, approach of classification, cast weld, resistance weld, fusion weld, solid state weld 3.1 Classification of welding processes There is another way of classifying welding and allied processes which is commonly reported in literature. Various positive processes involving addition or deposition of metal are first broadly grouped as welding process and allied welding processes as under: 1. Welding processes i. Cast weld processes ii. Fusion weld processes iii. Resistance weld processes iv. Solid state weld processes 2. Allied welding processes i. Metal depositing processes ii. Soldering iii. Brazing iv. Adhesive bonding v. Weld surfacing vi. Metal spraying This approach of classifying the welding process is primarily based on the way metallic pieces are united together during welding such as Availability and solidification of molten weld metal between components being joined are similar to that of casting: Cast weld process. Fusion of faying surfaces for developing a weld: Fusion weld process Heating of metal only to plasticize then applying pressure to forge them together: Resistance weld process Use pressure to produce a weld joint in solid state only: Solid state weld process 3.2 Cast welding process Those welding processes in which either molten weld metal is supplied from external source or melted and solidified at very low rate during solidification like castings.

  • Electrogas Welding
    Marine Construction and Welding Prof. Dr. N. R. Mandal Department of Ocean Engineering and Naval Architecture Indian Institute of Technology, Kharagpur Lecture No. # 34 Electrogas Welding (Refer Slide Time: 00:24) Today, we will start with another welding process which is referred to as electrogas welding. As we have seen, the electro slag welding, there the heat of the molten slag was used, that means the joule heating of the molten slag was used to generate the necessary heat for melting of the electrode as well as the parent metal. Here, in the electrogas welding, this is a kind of a, one can say a one-step, well, a kind of a development further from electro slag welding, but at the same time, somewhat similar to that of gas metal arc welding. In gas metal arc welding, we have seen the welding arc and the molten pool are shielded by an inert gas media. Here also, in electrogas welding, it is shielded by inert gas medium. So, this is also an arc welding essentially, it is not like, unlike, electro slag welding where there is no arc; it is the joule heating - the resistance heating - of the molten slag, that is what it is used, but in electrogas welding, it is again an arc welding; it is a fusion welding process, the heat source bearing the electric arc. And it is shielded by the gas, inert gas. So, the difference, what is the difference then between gas metal arc welding and this? The difference is in gas metal arc welding, the gas continuously keeps flowing, and that is used in all positional welding, but this is again a vertical welding process as that of as like electro slag welding, and here, the gas is fed; the gas remains in that position which is covered by that similar kind of shoes, what you have seen in case of electro slag welding.

This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces. Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, under water and in outer space. Regardless of location, welding remains dangerous, and precautions are taken to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light.

  • Applications and Trends of Electroslag Technology in Japan
    Welding Research Abroad, 32(2):27-34, 1986 APPLICATIONS AND TRENDS OF ELECTROSLAG TECHNOLOGY IN JAPAN Thomas W. Eagar INTRODUCTION Electrosiag welding and casting processes have been used in Japan for approximately two decades, with enerally good success. This report describes the amount of electrostag welding pzrformed In 3apan in 1981 along with typical product applications. It also describes briefly an electroslag casting and an electroslag overlay process, as well as recent trends in the usage of ektroslag technology. A brief discussion of the reasons fw the trends is also included. ELECTROSLAG WELDING Professor Isao Masumoto of Nagoya University reviewed the application of electroslag welding in Japan in 1981 [Masumoto et aZ. (1981 )]. His survey, which does not claim to be comprehensive, but appears to include most of the larger users of electroslag welding, indicates that more than 250 tons of electroslag weld metal was deposited in 1981. This was estimated to be 0.064% of the total volume of weld metal used in Japan; hence, in Japan, electroslag is a specialized process which is used for a limited number of applications. Nonetheless, Japanese industry has a wide range of experience with the process. Welds of 0.3 m to 9 m length have been made in section thicknesses ranging from 16 mm to 2.1 m. Welding currents range from 280 A to 8000 A with joint gaps from 18 mm to 50 mm. Materials welded include mtid steel, high strength steel, stainless steel, and Cr-Mo steels. As can be seen from Figure I, three-quarters of the weld metal is produced by the nonconsumable electrode guide process and most of this is used by the industrial machinery and pressure vessel industries.

The Act authorizes the National Institute for Occupational Safety and Health (NIOSH) to develop and recommend occupational safety and health standards and to develop criteria for improving them. By this means, NIOSH communicates these criteria both to regulatory agencies and others in the community of occupational safety and health. Criteria documents provide the basis for the occupational health and safety standards sought by Congress.
